What you describe is that they are unresolved - there was no evidence, verdict. That was all suppressed, including by attacking the prosecutor. Why not clear their names in court?

Prosecutors in every other circumstance wield almost unchecked power - except when the children of the powerful might end up in court. Name another prosecutor treated in this way.

Name another one that has acted so egregiously.

I don't know it was egregious; I think that was the media blitz by powerful people trying to shut them down.

Regardless, it happens all the time everywhere - witholding evidence, fabricated evidence, forced confessions, black site torture, endless harassment, etc. etc. What this DA allegedly did was relatively nothing.
